    Well - I found a transceiver set that claimed to go up to 100m, but it didn't. It covered the shorter distance - sometimes. It worked when I tested it at the track, but not on race day even after...

    HDMI over wi-fi?

    I'm pretty sure this wouldn't work, but I've been asked by a customer about sending a HDMI signal to a remote monitor. He's suggested that using HDMI-to-ethernet converters and wi-fi extenders would...

    flickering

    By "marginal", do you mean charge/discharge voltage fluctuations? 24 - 30 VDC in my case and sometimes a bit outside those values. Or do you mean the rapid on/off in PWM modes in the charge...

    Thanks, hinekadon - I don't have the skills to micro-solder, but if the flickering gets too bad, I'll replace them, then pull them apart and see if I can see any bad solder joints. At least I'll know...

    LED flickering

    So, I'm gradually replacing various lighting items with LEDs. A pair that I put in some months ago has started flickering on startup.

    I'm off-grid with PV, lead-acid batteries, sine-wave inverter,...

    I think LSemmens is right. The best solution, the simplest, is to move it away from the heat altogether. I *could* also just point a fan at it without heatsinks or ducting or drilling holes. ...

    Hi - I can't move the motor away - it's an electromagnetically-powered impeller that's motivated by the rotating magnetic field in the pump motor. The impeller is also "part" of the motor pump...

    Thanks everyone for your thoughts - I think it's "new pump" time. Still, it was worth some time and effort to explore it. Cheers.

    Pump update

    OK, pump's out. When I connect 12V directly to the red (+ve) and black (-ve) leads, the impeller is showing the same characteristics as before. It twitches, and only spins when I give a helping...

    Thanks everyone for your suggestions. I'm going to remove the pump from the loop today and see what I can come up with. This is obviously more complex than replacing a single cap.

    Yep - there are two PCBs in there. I think the first one, where the DC supply leads and the cap are attached, is the "soft-start" mechanism, and the second board is the one that controls the...

    Close, but not quite. I see from the ebay description that one is 25mm in length. I just measured my original and it's 35mm. The replacement I bought is 30mm, so it's more like 0.5cm shorter than the...

    It's a system that pumps hot water through a towel rail in the bathroom. It "interrupts" the HWS heating loop,...
